Calculate the mass of zinc iodide formed when you have 1.o grams of zinc metal and 1.0 grams of iodide crystals
There are two reason why the enols of beta-dicarbonyl compounds, such as pentane-2,4-dione are relatively stable. One is that they are conjugated and the pi-electron overlap due to the conjugation provides additional stability.
